To all whom; it may concern:

Be it known that I, PETER E. EmoKsoN, .a citizen of the United States,and a resident of Port Chester, in the county of Westchester and Stateof New York, have invented a new and Improved Hose-Clamp, of which thefollowing is a full, clear, and exact descrlption.

This invention relates to hose clamps of the character described andclaimed in Letters Patent of .the United States issued .to

me on February 9,, 190.9, No. 912,097, the.

invention comprising a band of tough flexible metal, the ends of whichoverlap .or' cross each other, and the provision of a peculiar means forsupporting .a clamping screw whose function is to spread the crossedends of the band to thereby tighten the band upon j E 13, its threadedbore being in al'rnement with the hose or other means being clamped.

Among the objects of the present inven-f tion is to so improve this typeof hose clamps as to increase the efliciency thereof and cheapen theirproduction.

A further object of the invention is to make the hose clamp more compactin proportion to its general contour and strength and thereby render thedevice less liable to damage or disturbance from outside o'bstructionsor influences.

The foregoing and other objects of the invention will hereinafter befully described and claimed and illustrated in the drawings accompanyingthis specification in which like characters of reference indicatecorresponding parts in all the views, and in which Figure 1 is a planview of the clamp made in accordance with a preferred embodiment of thisinvention; Fig. 2 is a vertical central transverse section on the ling22 of Fig. 1; and Fig. 3 is a side elevation, partly in section, on theline 3-3 of Fig. 2.

Referring particularly to the drawings, I show at 10 a band of suitabletough flexible metal preferably of uniform thickness throughout. One end11 of the band constitutes a head substantially rectangular in outline,as indicated in Fig. 1, and is so punched or stamped as to form an eye11. Said band, as it leaves one end of the head, is slightly tapered andit terminates at its other end in a cup 12 which is adapted to passthrough the aforesaid eye while assembling the clamp or putting it inplace, the

flexibility of the metal permitting such op eration. The cup 12 ispressed or' stamped out of the same bod .of metal as the remainingportions .of t e hand.

The metal punched out to form the eye 11' constitutes a tongueconstructed or bent into a substantially U-shaped socket 13., one sidemember 13 of the socket remain-mg integral with the freeend of the head11 and the .other side member 13 of the socket or free .end of thetongue of metal extending inwardly through the eye 11 substantiallyparallel to the side member 13. The side members 13 and 13" are ,unchedto form a'lined holes 14: and the on of the head adjacent thereto isswaged downwardly at 15 substantially cylindrically, the axis of ,thecylinder being coincident with the .axes of the holes 14.

A 16 is seated and held in the socket I the aforesaid holes of thesocket 13, and cooperating with said nut is a clamping screw 17 whichpasses through the holes. and nut and bears at its inner end in said cup12. The loop or crotch'of the socket 13, being on the outer side of the,clamp ring or band 10, provides a' neat, compact, and exceedingly strongconstruction having no sharp or angular projections. It will beapparent, therefore, that not only will the nut 16 be held in its socketby means of the screw, but the arrangement of the side members 13' and13" of the socket will cooperate in such a manner with the screw as toprovide a device having the capability of withstanding all.of thestrains to which the clampwill be subjected. In other words, the screwis adapted to bear not only upon the cylindrical portion 15 of the endof the head, but

also upon the free end of the side member .13" of the socket, making asubstantial an chorage for the screw in its cooperation with Y the otherparts of the band. It will be impossible, therefore, under any ordinarycircumstances, for the screw to be distorted from its intended position.It is to be noted also that the clampingfscrew will lie substantiallysnugly against that portion of the band which engages the hose or otherdevice being clamped, whereby the maximum effective strength of theclamp will be attained.

A clamp made in accordance with this invention will not only hepossessed of the maximum strength in proportion to the amount ofmaterial employed, but the element of cheapness of construction ismaterially enhanced by reason of the fact that there Will be practicallyno Waste metal in its formation. The metal stamped out to form the eye11' will constitute the walls of the socket member 13 and no alterationof shape thereof will be necessary beyond the bending up to bring thetwo sides at right angles to the longitudinal axis of said head. Thedepression 15 also may be formed in the act of pressing the metalwithout materially distorting the other portions of the head. The screwand nut may be of any conventional construction and no alterationthereof is necessary to adapt them to the band in the manner above setforth.

The operation of the clamp may be briefly described as follows: The nut16 being slipped into the socket 13 from the inner side of the head andthe screw placed in position With its point leading through the nut andholes 14:, the band will be put in place with the cup end passed aroundthe object being clamped and slipped into or through the eye 11. Thescrew is then turned to bring its point into the cup and the screw Willbe turned obviously to a degree suficient to efiect the proper clampingresult.

remote Having thus described my invention, What I claim as new anddesire to secure by Letters Patent, is

The herein described hose clamp comprising, in combination, a metallichand, one end of which constitutes a head, a portion of the metal of thehead being punched out as a tongue and bent to form a substantiallyU-shaped socket, one end of the tongue con stituting a Wall of thesocket being integral with the head and the free end of the tongueconstituting the other Wall of the socket, and the other end of the bandbeing adapted to pass through the eye formed by the bending out of saidsocket structure, and means to force the ends of the band apart, saidmeans comprising a screw passing through both Walls of said socket andbearing upon the other end of the band.

In testimony "whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
